Abstract

L'invention concerne un procédé de codage vidéo reposant sur un mode de codage cadre/champ adaptatif. En vue d'éviter une détérioration de la qualité de l'image et de l'efficacité de compression lorsqu'une séquence vidéo contient beaucoup de mouvements ou au contraire des images quasiment dépourvues de mouvement, un code amélioré de durée double de défilement en temps réel est proposé. Pendant le premier défilement, aucun train de séquences vidéo n'est généré, mais des résultats statistiques sont calculés et puis attribués à la seconde durée en vue d'optimiser pendant cette seconde durée l'attribution du débit binaire et la gestion du tampon. Ce procédé de codage amélioré de durée double se solde par une augmentation de l'efficacité de compression d'environ 10 %.
